Skin Risks: Summer Skin Hazards and How to Avoid Them

What is the prognosis of a poison ivy, oak, or sumac rash?

In general, the prognosis is excellent. In the vast majority of cases, the rash will improve on its own within one to three weeks without any complications, and all that is necessary is self-care at home with treatment to relieve the itching.

Is it possible to prevent a poison ivy, oak, or sumac rash?

There are measures that can be taken to help prevent the rash caused by exposure to these plants, including the following:

  • Learn to recognize these plants in order to avoid contact with them.
  • Wear protective clothing that covers the skin, including gloves, long sleeves, long pants, and boots if in a high-risk area.
  • If the possibility of contact with these plants exists, apply commercially available barrier creams to the skin, which may help prevent or lessen the exposure to the toxic plant oils. These products usually contain bentoquatam (IvyBlock) and should be applied before going outdoors.
  • Do not burn these plants, as this can release urushiol into the air.
  • Carefully remove these plants if they are growing near one's home. Be sure to wear protective clothing and gloves.
  • Thoroughly wash clothing or any other objects that may have come into contact with these plants, as they can retain the plant oil and cause a rash if worn or touched.
  • If a pet has been exposed to these plants, wear protective gloves and give them a bath.
